The stamp act of 1765 angered colonists because a.) british citizens in the colonies did not have to pay the taxes. b.) the tax was so high it prevented people from buying paper. c.) they did not have representation in parliament. d.) tax collectors were able to take people’s property.

The answer would be choice C) the colonists had no representation, since the main reason for the outrage in British taxation was "Taxation without representation" which represents the Parliament's tyranny. The taxes make the colonists feel as if they are being controlled without reason by the British and oppressed without having their say in many things the British does such as the heavy taxation.
